(2018). Modeling and trade-off analysis of a capacitive silicon Mach-Zehnder modulator for telecom applications. In 2018 SBFoton International Optics and Photonics Conference (SBFoton IOPC). Campinas, Brazil.http://hdl.handle.net/10198/19466This paper presents a capacitive modulator design and modeling using poly-si and silicon technologies. We propose a methodology involving the entire modulator design process, from the optical design, charge distribution calculation and small-signal RF analysis. Thus, in the case of silicon photonics modulators, the paper proposes means to optimize the trade-offs among several figures of merit. It is shown that high bandwidth operation (>30 GHz) can be achieved by sacrificing a little the modulation efficiency.engSilicon photonicsMach-zehnderCapacitive modulatorModal analysisOptical devicesconference paper10.1109/SBFoton-IOPC.2018.8610918
